Which radars cover Hammond?

The closest NEXRAD Doppler radar is KHDC (Hammond, LA), about 3 miles east-northeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.

Radar	Distance	Lowest beam over Hammond	View
KHDC Hammond, LA	3 mi east-northeast	100 ft	Excellent — the lowest scan sees close to the ground
KLIX New Orleans, LA	39 mi east-southeast	2,600 ft	Excellent — the lowest scan sees close to the ground
KDGX Jackson, MS	126 mi north-northeast	13,700 ft	Limited — the beam overshoots the lowest part of storms

Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
